Winds topping out at 90 kilometers per hour fanned the brush fire’s flames and caused the blaze to spread quickly.

Officials with cycling’s governing body, the Union Cycliste Internationale, acknowledged the fire, stating it was under control. They would not confirm whether or not the Olympic mountain biking venue sustained damage.

“The UCI is aware that there was a fire this afternoon in the vicinity of the Rio 2016 mountain bike course,” the statement read. “It is understood the fire is now under control. Assessment of any potential impact on the mountain bike course will be made tomorrow.”

Though the UCI has yet to confirm whether there was damage done to the Olympic mountain biking venue, Canadian Cyclist reported that the venue had caught fire during the day. The publication also noted that the fire was caused by a controlled garbage burn that got out of control.
